Gait Flashcards
Gait exam in children with CP
increased co activation of muscle groups disrupting the synergetic neuromuscular control needed for gait
Ankle lever arm disfunction
to walking decreases ankle power by 50% (requires half the strength than heal-toe walking)
beneficial compensation for children with CNS dysfunction
Joint and Bony abnormalities
Internal/external lever arm become distorted because of bony or positional deformities (ex. femoral antiversion, ER of tibia, equinovalgus, genu recurvatum
Jump knee gait
ankle in equinus in late stance
knee and hip hyperflexion in early stance
pelvis normal
Equinus gait (toe walking)
True: ankle in equinus during stance
full knee/hip extension
Apparent: ankle normal ROM, knee and hip hyperflex in stance
Crouch gait
ankle in excessive dorsiflexion through stance, knee/hip hyperflexed, pelvis normal, ant/post/tilt
Stiff-knee gait
reduction in knee flexion during swing, coupled with hip circumduction
Green light pediatric interventions
mobility training
treadmill walking
partial BWSTT
Yellow light pediatric interventions
AFOs
Fitness training
Estim
Casting
Partial BWSTT
Physical Activity
Trendelenburg gait (stance)
GLut med weakness
Lateral Trunk bending (stance)
glut med weakness
Excessive Knee flexion (stance)
Knee wobbles or buckles- weak quads
Knee remains flexed- knee flexor contracture
compensatory forward trunk bending
Foot drop (swing)
weak/delayed contraction of DF
Decreased clearance (swing)
weak/delayed hip flexors and plantar flexion push off
Dynamic gait interventions
walking with head turns
walking over and around obstacles
walking while carrying objects
walking with attentional challenge
Instructive learning
explicit strategic instruction
Ex: pick up foot, land on heal
Reinforcement learning
reward based instruction
Ex: you will walk faster
Use dependent learning
Repetition based, task specific massed practice
Ex: 10,000 steps on the treadmill
Sensorimotor adaption learning
Sensorimotor prediction errors
predicted vs actual movement mismatch
BWSTT population
unable to ambulate independently without significant assistance
Patient early (<3 months) in recovery post stroke with significant gait abnormalities/postural instability
nonfunctional ambulators with goal of walking to improve CV function
BWSTT Dosing
as little WB as needed
mod-high intensity (70-85% HRmax)
transition to overhead harness without BWS as soon as possible/safe
CPG for chronic stroke
Strong evidence shown for mod-high intensity walking training with full body weight
Virtual reality for walking and balance training
Orthotics define
any externally applied device to an existing body part that improves function (AFO)
stabilize weak areas of joints
limit/aid motion across joints
Neuroprosthetics
a device which helps pr augments the subject sown nervous system
FES
NMES vs FES
NMES:
produces muscle contraction to generate muscle force
FES:
attainment of functional movement
applied during activity
Evidence for FES
positive initial effect on gait speed
positive effect on walking function
Evidence for AFOs
positive affect on walking function
improve foot drop and ankle/knee kinematics
